ammunition, explosives, pyrotechnics, propellants, and oxidizers or related
devices containing these materials, unless such a system will aggravate the
hazard. The following guidelines for automatic sprinkler protection must apply:
6-9.1.1.1
Where exposed thermally energetic materials are handled that
have a high probability of ignition, a large thermal output and a high probability of
causing personnel injury, operations must be protected using ultra high-speed
deluge systems. Ultra high-speed deluge systems have a response time of 100
milliseconds (ms) or less. Response time is measured from the time that an
energy source is presented to the detector to the time of initial water flow from
the critical nozzle, which is normally the nozzle closest to the hazard. Ultra high-
speed detectors usually consist of preprimed water delivery system, optical flame
detectors, and electronic controller. Paragraph 6-9.2 provides guidance on ultra
high-speed deluge systems. NFPA 15, Water Spray Fixed Systems for Fire
Protection, and the NFPA Handbook provide additional information on ultra high-
speed deluge systems.
6-9.1.1.2
Provide high-speed (operation of 500 milliseconds or less),
preprimed deluge systems wherever exposed explosives, pyrotechnics, or
propellants are processed or stored in ordnance production facilities. Complete
protection of such locations is essential.
6-9.1.1.3
Provide ordinary deluge systems, wet-pipe systems, or preaction
systems in other areas or auxiliary sections of buildings in which processing of
explosives, pyrotechnics, or propellants takes place.
6-9.1.1.4
Provide ordinary deluge systems, wet-pipe systems, or pre-action
systems in other areas or auxiliary sections of buildings in which storage of
explosives or propellants takes place.
6-9.1.1.6
Provide wet-pipe sprinkler systems in other areas or auxiliary
sections of buildings if separated by fire partitions.
6-9.1.1.7
Provide wet-pipe or pre-action sprinkler systems where missile
assembly inspection or storage is carried on and where the propellant is confined
within the missile, or warheads are present. Similar protection must be provided
for torpedo and air underwater weapons shops.
6-9.1.1.8
Heat detection equipment of any type is acceptable if equipment
meets the operating time limitations and is suitable in other respects, such as
complying with explosion-proof requirements. When pneumatic-type detection
equipment is used, not more than three detectors, and preferably only one, must
be on a single circuit. The detectors must be in the same heat influence area.
6-9.1.1.9
All fire protection systems protecting ordnance operations must
have complete supervision so that any deficiency that develops that would affect
